Molecular detection and genotyping of human herpes virus 8 in blood donors in Congo.

Objectives: Human herpesvirus 8 (HHV8) is rarely studied in Congo, despite its prevalence in Africa. Among healthy individuals, HHV-8 does not always lead to a life-threatening infection; however, in immunocompromised individuals, it could lead to more severe disease. The distribution of HHV-8 genotypes varies depending on ethnicity and geographic region.

: Next-generation sequencing sheds light on Witkop's classification.

Amelogenesis imperfecta (AI) is a heterogeneous group of genetic rare diseases disrupting enamel development (Smith et al., Front Physiol, 2017a, 8, 333). The clinical enamel phenotypes can be described as hypoplastic, hypomineralized or hypomature and serve as a basis, together with the mode of inheritance, to Witkop's classification (Witkop, J Oral Pathol, 1988, 17, 547-553).

Spatiotemporal changes in substantia nigra neuromelanin content in Parkinson's disease.

This study aimed to investigate the spatiotemporal changes in neuromelanin-sensitive MRI signal in the substantia nigra and their relation to clinical scores of disease severity in patients with early or progressing Parkinson's disease and patients with idiopathic rapid eye movement sleep behaviour disorder (iRBD) exempt of Parkinsonian signs compared to healthy control subjects. Longitudinal T1-weighted anatomical and neuromelanin-sensitive MRI was performed in two cohorts, including patients with iRBD, patients with early or progressing Parkinson's disease, and control subjects. Based on the aligned substantia nigra segmentations using a study-specific brain anatomical template, parametric maps of the probability of a voxel belonging to the substantia nigra were calculated for patients with various degrees of disease severity and controls.

MRI of neurodegeneration with brain iron accumulation.

Purpose Of Review: The diagnosis of neurodegeneration with brain iron accumulation (NBIA) typically associates various extrapyramidal and pyramidal features, cognitive and psychiatric symptoms with bilateral hypointensities in the globus pallidus on iron-sensitive magnetic resonance images, reflecting the alteration of iron homeostasis in this area. This article details the contribution of MRI in the diagnosis by summarizing and comparing MRI patterns of the various NBIA subtypes.

Recent Findings: MRI almost always shows characteristic changes combining iron accumulation and additional neuroimaging abnormalities.

Placental Overexpression of Soluble CORIN in Preeclampsia.

Preeclampsia (PE) is a hypertensive disease of pregnancy associated with substantial maternal and fetal morbidity and mortality. CORIN is a transmembrane type II serine protease expressed in cardiomyocytes that converts pro-atrial natriuretic peptide into atrial natriuretic peptide, a cardiac hormone that regulates blood pressure. High levels of soluble CORIN have been reported in PE and are supposed to be cardiac in origin.

Clinical factors predictive for histological aggressiveness of basal cell carcinoma: A prospective study of 2274 cases.

Introduction: Since surgery is the first-line treatment for basal cell carcinomas (BCC), the histological aggressiveness of the disease must be clinically predicted in order to apply optimal safety margins that ensure a high rate of complete resection while minimising the risk of recurrence.

Objectives: To evaluate clinical predictive factors of histological aggressiveness of BCC, we conducted a national prospective multi-centre study.

Methods: All consecutive patients presenting for BCC surgery were included, and standardised clinical data collected, and slides were submitted for review.

GENIPSO: a French prospective study assessing instantaneous prevalence, clinical features and impact on quality of life of genital psoriasis among patients consulting for psoriasis.

Background: Genital psoriasis is often under-recognized.

Objectives: To assess the instantaneous prevalence of genital psoriasis and describe its clinical features, association with a particular subtype of psoriasis and its impact on general and sexual quality of life (QoL).

Methods: GENIPSO is a prospective study conducted by private and hospital-based dermatologists.

Bevacizumab and temozolomide in patients with first recurrence of WHO grade II and III glioma, without 1p/19q co-deletion (TAVAREC): a randomised controlled phase 2 EORTC trial.

Background: Bevacizumab is frequently used in the treatment of recurrent WHO grade II and III glioma, but without supporting evidence from randomised trials. Therefore, we assessed the use of bevacizumab in patients with first recurrence of grade II or III glioma who did not have 1p/19q co-deletion.

Methods: The TAVAREC trial was a randomised, open-label phase 2 trial done at 32 centres across Europe in patients with locally diagnosed grade II or III glioma without 1p/19q co-deletion, with a first and contrast-enhancing recurrence after initial radiotherapy or chemotherapy, or both.

Lower-limb Ulcers in Systemic Sclerosis: A Multicentre Retrospective Case-control Study.

Lower-limb ulcers in systemic sclerosis patients are rarely reported. The aim of this study was to describe the main causes and outcomes of lower-limb ulcers in systemic sclerosis patients and to assess factors associated with ischaemic causes (arterial disease and/or microvascular impairment). A retrospective, multicentre, case-control study was conducted in 2013 and 2014, including 45 systemic sclerosis patients presenting lower-limb ulcers between 2008 and 2013.

What Are the Determinants of Dental Care Expenditures in Institutions for Adults With Disabilities? Findings From a National Survey.

Objective: To analyze the determinants of dental care expenditures in institutions for adults with disabilities.

Design: Health and disability survey and insurance database.

Setting: Institutional setting.

Computerized cognitive stimulation and engagement programs in older adults with mild cognitive impairment: comparing feasibility, acceptability, and cognitive and psychosocial effects.

Purpose: Mild cognitive impairment (MCI) is associated with a higher risk of dementia and is becoming a topic of interest for pharmacological and nonpharmacological interventions. With advances in technology, computer-based cognitive exercises are increasingly integrated into traditional cognitive interventions, such as cognitive training. Another type of cognitive intervention involving technology use is cognitive engagement, consisting of involving participants in highly motivational and mentally challenging activities, such as learning to use a form of new digital technology.

The oncologic burden of hepatitis C virus infection: A clinical perspective.

Answer questions and earn CME/CNE Chronic hepatitis C virus (HCV) infection affects millions of people worldwide and is associated with cancer. Direct-acting antivirals (DAAs) have changed HCV treatment paradigms, but little is known about the management of HCV infection in patients with cancer. The substantial burden of HCV infection and the inconclusive evidence regarding its detection and management in patients with cancer prompted the authors to review the literature and formulate recommendations.
